FRIED-CAKE FORMING AND CUTTING MACHINE.

Specification of Letters Patent.

Patented Oct. 18, 1921.

Application filed November 8, 1920. Serial No. 422,739.

T 0 all whom it may concern.

Be it known that I, JAY B. WINANS, a citizen of the United States, residing in South Bend, St. Joseph county, Indiana, have invented certain new and useful Improvements in Fried-Cake Forming and Cutting Machines, of which the following is a specification.

My invention relates to machines for forming and cutting fried cakes or doughnuts.

An object of my invention is to produce a machine of the character described in which a plurality of forming dies and cutters are provided for the production of a great quantity of doughnuts Within a limited period of time. Other objects of my invention are mentioned and described herein.

The preferred embodiment of my invention is illustrated in the accompanying drawings in which Figure 1 is a side elevation of the machine in which the invention is incorporated; Fig. 2 is a bottom plan view of the same machine; Fig. 3 is asection taken on the line 33 of Fig. 2; Fig. 4 is a fragment showing one of the forming dies in perspective; Fig. 5 is a top plan view of the machine; and Fig. 6 is a section taken on the line 66 of Fig. 2.

Similar numerals of reference indicate like parts throughout the several views on the drawings.

Referring to the drawings in detail, the numerals 1 and 2 indicate opposed frame side plates between which the frame bottom plate 3 is arranged, the side plates being secured together by the spacer rods 4. and 5, the ends whereof may be provided with the nuts 6, 6. A pair of corrugated rotary feed rollers 7 and 8 are mounted within the mztthine frame and upon shafts 9 and 10, the ends of said shafts being suitably journaled inthe frame side plates 1 and 2 to effect a parallel relation between said shafts.

A feed hopper 11 may be mounted in the machine frame and supported on the side plates 1 and 2 by bracket 12 which engages the upper edge of one of said frame plates. The hopper 11 may be held against displace- I ment by. a coil spring 13 anchored to the plate 2 at 1 1 and adapted for detachable engagement with a hook 15 fixed in the exterior of the hopper.

One end of each of the feed roll shafts 9 and 10 projects beyond the outer face of the frame plate 2 to carry the intermeshing gears 16 and 17 rigidly secured thereon. A driving pinion 18, meshing with the gear 16, is rigidly mounted upon the revoluble stub shaft 19, the latter being suitably journaled in the frame plate 2 and with which a handle or crank 20 is rigidly connected for operating the former. Obviously, rotation of the pinion 18 effects rotation of the gears 16 and 17, whereby the feed rolls 7 and 8 are driven.

An idler gear 21 is revolubly mounted upon a headed stub I shaft 22 detachably mounted in any suitable manner at one end of the adjustable carrier member 23 which is longitudinally slotted at 2 1 and movable and adjustable longitudinally on the stud 25 screwed into the frame plate 2. The gear 21 may mesh with the gear 26 which is rigidly mounted upon a cutter driving shaft 27 which is suitably journaled in the bearings 28 and 29 mounted on the under side of the frame bottom plate 3, said shaft being adapted to drive cutter elements, as hereinafter described. The use of the member 23 enables the substitution of smaller or larger gears for the gear 21 to effect a change of speed in the cutter driving shaft 27, and thereby regulate the speed of the cutter elements, as hereinafter described.

The frame bottom plate 3 may be rectangular or otherwise suitably formed, and is suitably apertured to carry the four detachable forming dies 30, 31, 32 and 33, respectively, each of which dies may consist of a hollow cylindrical member 34 screw threaded into the bottom plate aperture at 35 (Fig. 3), and a' separate piece central plug member 36 to form the annular channel 37 therein. The die plug 36 is rigidly secured centrally of the bore of the member 34 by a thin knife blade rib 38, the opposite ends whereof are rigidly secured in the wall of the member 34 and upon which said plug is rigidly secured.

The dies 30, 31, 32 and 33 are preferably grouped quadrangularly around a conical dough guide member 39 which is rigidly fastened in any suitable manner to the upper surface of the floor plate 3, the point of said conical guide member being disposed midway between the feed roller shafts 9 and 10 and centrally of the dies 30, 31, 32 and The numerals 40 and 41 indicate a pair of opposed baffle plates removably disposed beneath the rolls 7 and 8, respectively, and transversely of the frame and connecting the side plates 1 and 2, said baffle plates being outwardly inclined from a point directly beneath the feed rolls, and being adapted to form a conduit or channel above the dies 30, 31, 32 and 33. The lower edge of each of the ba'liie plates 40 and 41 engages an abutment member 42 rigid with the frame, and the upper end of each of said baffle plates engages a stud 43 rigid with a frame side wall or plate, the studs on' one side only being shown. ,The plates 40 and 41 are normally held in engagement with the members 42 and 43 by a coil spring 44 connected with the plate at 45 and detachably connected with a hook 46 anchored in the frame. The plates 40 and 41 are readily re- 'moved by disconnecting the coil springs from the hook 46.

The mouth or inlet of the channel 37' of each of the dies 30, 31, 32 and 33 may be opened or closed by a pair of opposed sliding gates 47 and 48 adapted to operate in suitable guideways 49 and 50, each of which gates controls two of said dies and may have a handle 51 for the manual actuation there of. In Fig. 3 the gate 48 is shown closing two of the dies. The shaft 27 extends to a point adjacent the center of the bottom plate 3 and carries a bevel pinion 52 rigid therewith, which pinion meshes with the bevel wheel 53 rigidly mounted upon a vertical shaft or spindle 54, the latter being jourmled in the bearing 55 formed in the cone 39, the platc'3 being suitably apertured-to permit the passage of the shaft into said bearing. The bevel wheel 53 and shaft 54 are supported and held against longitudinal displacement from the bearing by a T shaped bracket 56 rigidly secured tov the ex terior or under surface of the plate 3 by screws 57, 57, said bracket serving as a step bearing for the bevel wheel 53, Fig. 6. y

The bracket 56 is suitably apertured at 58 to permit the passage of the shaft 54 to effect an extension of the latter beyond and below said bracket to enable the block 59 to be rigidly mounted thereon,- said block be? ing vertically adjustable on said shaft by a set screw 60 adapted to engage the shaft for securing saidblo'ck in any desired position within short limits. A pair of substantially U shaped 'cutter'bairs 61' and 62 are carried by the block 59, each of said bars having a lateral 63 detachably arranged in a socket 64 formed in said block and detach ably secured therein by a set screw 65. The cutter bars 61 and 62 are arranged upon opposite sides of the block 59 and each carries a cutter wire 66, the outer end of said wire being rigidly secured at 67, the inner end thereof being anchored to a screw or pin 63 fixed in the block 59.

A handle 69 may be attached to any portion of the frame for transportation of the machine, and a bracket 70 may be provided for bolting the machine in a fixed position for the operation thereof. Numeral 71 indicates an apron of sheet metal, or otherwise, adapted to be fastened to the machine frame and to shield the operator from the splash of the greasy liquid frying material when the doughnuts fall therein from the cutters.

I claim 1. A doughnut cutter comprising a frame provided with a bottom plate; dough guiding means arranged substantially centrally of said bottom plate; a plurality of forming dies arranged in a series around said guiding means; means for feeding the dough to said dies; means for cutting the dough as it emerges from the dies; and means for closing the dies to prevent the feed of the dough thereto.
